BACKGROUND

Different exercising devices such as ergometers, gym exercising devices, fitness devices, sports devices, weight lifting devices, exercise bikes, treadmills, rowing machines, cross trainers, etc. are known. Some of the known exercising devices are often equipped with an internal display, a user interface and/or a memory, for example exercise bikes or treadmills. Further, various mobile devices are known by means of which information can be stored, processed and/or displayed. The mobile devices typically comprise a user interface such as a touchscreen, a keyboard or at least one button. Examples of such devices are smartphones, tablets, smartwatches and wrist-watches.

User sessions, such as training sessions, may be recorded, for example in notebooks, spreadsheets or other suitable media. Recorded training sessions enable more systematic training, and progress toward set goals can be assessed and tracked from the records so produced. Such records may be stored for future reference, for example to assess progress an individual is making as a result of the training. An activity session may comprise a training session or another kind of session.

Personal devices, such as, for example, smart watches, smartphones or smart jewelry, may be configured to produce recorded sessions of user activity. Such recorded sessions may be useful in managing physical training, child safety or in professional uses. Recorded sessions, or more generally sensor-based activity management, may be of varying type, such as, for example, running, walking, skiing, canoeing, wandering, or assisting the elderly.

Recorded sessions may be viewed using a personal computer, for example, wherein recordings may be copied from a personal device to the personal computer. Files on a personal computer may be protected using passwords and/or encryption, for example.

Personal devices may be furnished with sensors, which may be used, for example, in determining a heart-beat rate of a user during a user session. A recorded heart-beat rate of a user may be later observed using a personal computer, for example.

Document FI 20155989 discloses an apparatus comprising a memory configured to store first-type sensor data, at least one processing core configured to compile a message based at least partly on the first-type sensor data, to cause the message to be transmitted from the apparatus, to cause receiving in the apparatus of a machine readable instruction, and to derive an estimated activity type, using the machine readable instruction, based at least partly on sensor data.

Considerable advantages are obtained by means of certain embodiments of the present invention. An apparatus comprising at least one processing core and at least one memory including computer program code is provided. According to certain embodiments of the present invention, it can be determined that an exercising device and a mobile device are engaged with each other based on correlated sensor data streams received from the exercising device and the mobile device. An activity type of a user can be estimated by the apparatus based on the received sensor data streams of the exercising device and the mobile device. The apparatus can be remotely accessible by a person in order to analyse a user session in real time or at a later stage. For example, the apparatus may be connected with the internet. A client connected to the apparatus may receive the sensor data streams and may be configured to cause pairing of the mobile device and the exercising device based on the correlated data streams or based on instructions input by a person.

After providing indication to the exercising device and the mobile device that the devices are engaged with each other, the exercising device can participate in pairing with the mobile device and the mobile device can participate in pairing with the exercising device according to certain embodiments of the present invention. The mobile device and the exercising can form at least temporarily a unit in which the mobile device serves as a display, a user interface and/or a memory of the exercising device. According to certain embodiments of the present invention, the mobile device serves as a display of the exercising device. The mobile device may serve as the only display or as an additional display of the exercising device during the time period of a user session. According to certain other embodiments of the present invention, the mobile device serves as a user interface of the exercising device. The mobile device may serve as the only user interface or as an additional user interface of the exercising device during the time period of a user session.

A mobile device and the exercising device can temporarily form a unit during the time period of a user session, a training session or a sports session. According to an embodiment, an app which is related to a specific exercising device can be stored in the memory of the mobile device of a user. Settings of the app can be personalized. For example, when the user is bringing his/her mobile device to a gym, the user can start a user session using his/her own personalized settings. Personalized settings may include information about age, weight, height, gender, body mass index, maximum performance capacity, activity parameter, previous energy expenditure and maximum heart rate, for instance. Also personalized exercise-guidance parameters such as an energy expenditure target, heart rate zones, activity zones, anaerobic threshold, fitness classification identifier and/or dehydration warning limits may be stored on the mobile device. Personalized data determined by sensors of the exercising device can further be stored in the memory of the mobile device and/or in the internet. Further, personalized data determined by sensors of the mobile device can be stored in the memory of the mobile device and/or in the internet. Determined data of the user, for example movement data or heart-beat rate data, can then be analysed at a later stage subsequent to the user session, training session or sports session. When another user is using the exercising device in the gym, his/her mobile device and the exercising device temporarily form a unit during the time period of another user session. Personalized settings can be used by this other user and personalized data can be stored in the memory of the respective mobile device and/or in the internet for further analysis. Consequently, it is not necessary to store any personalized data on the memory of the exercising device according to certain embodiments of the present invention.

According to another embodiment, no program code or a minimum amount thereof needs to be installed on the mobile device such as a wrist watch. The mobile device serves as a display and/or user interface for the exercising device. The procedure is controlled by the exercising device or the apparatus. Minimum system requirements are required for the mobile device. According to this embodiment, the input data is processed by the exercising device or the apparatus. The bidirectional communication link between the mobile device and the exercising device or apparatus may be used to enable the exercising device or apparatus to act as a server having control over the user interface and the mobile device to act as a client whose content is fully or at least partially controlled by the exercising device or apparatus.

Receiving a first sensor data stream from the exercising device, receiving a second sensor data stream from the mobile device, correlating the first data stream with the second data stream, determining that the exercising device is engaged with the mobile device, and providing indication to the exercising device and the mobile device that the devices are engaged with each other can take place automatically, thus providing to the user a comfortable user experience.

According to certain embodiments, a temporarily combined unit can share a classification task. I.e. the exercising device has its own classification task to produce semantic events like ‘lift’, ‘release’, ‘step’ etc. Similarly, the mobile device has its own classification task to produce semantic events. The system creates a more comprehensive analysis of the user's actions to provide e.g. a deeper understanding of the user's biomechanical accuracy.

Certain embodiments of the present invention are applicable with regards to health care, in industry, in working environments, in sports, and the like.

EMBODIMENTS

In FIG. 1 a schematic top view of an apparatus 18 in accordance with at least some embodiments of the present invention is illustrated. The apparatus 18 comprises at least one processing core and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processing core, cause the apparatus 18 at least to receive a first sensor data stream from an exercising device 2, receive a second sensor data stream from a mobile device 1, correlate the first data stream with the second data stream, determine that the exercising device 2 is engaged with the mobile device 1, and provide indication to the exercising device 2 and the mobile device 1 that the devices 1, 2 are engaged with each other. In other words, the apparatus 18 is capable of estimating that a user 6 is using a specific exercising device 2 by correlating sensor data received from the mobile device 1 and sensor data received from the exercising device 2. The apparatus 18 is capable of estimating an activity type of a user 6, for example running, based on the correlated data streams.

The mobile device 1 may be a wrist-watch, for instance. The exercising device 2 may be a treadmill, for instance. The apparatus 18 may be, for example, a server or server infrastructure. The apparatus 18 is configured to store and process sensor data received from the exercising device 2. Further, the apparatus 18 is configured to store and process sensor data received from the mobile device 2. Of course, the apparatus may be also configured to store and process sensor data received from a wearable sensor or any other external sensor, for example a MOVESENSE sensor. Such sensor data may be wirelessly transferred to the apparatus 18 directly or to at least one of the mobile device 1 and the exercising device 2 first and then to the apparatus 18.

According to a certain embodiment, an external sensor (not shown), for example a MOVESENSE sensor, is attached to a user and connected to the mobile device 1, for example a wrist watch 1. When the user comes to an exercising device 2, the mobile device 1 automatically displays information. Simultaneously, the mobile device 1 receives instructions from the exercising device 2 and/or apparatus 18. However, also the exercising device 2 and/or apparatus 18 may receive data from the mobile device 1 and/or the external sensor. The data may, for example, include personal data, sensor data and/or external sensor data. The data is typically processed by the exercising device 2 and/or apparatus 18. This kind of user experience is automatically created. When the user changes the exercising device 2, for example in a gym, the displayed information on the display of the mobile device 1 also automatically changes. The exercising device 2 can additionally receive further data from a server or via the internet. External sensor data can be analysed by the exercising device 2 and/or apparatus 18 and content, for example information derived from the sensor data, can be automatically displayed on the mobile device 1. In such a situation, the exercising device 2 may be used to enable the exercising device 2 to act as a server having control over the user interface and the mobile device 1 to act as a client whose content is fully or at least partially controlled by the exercising device 2

The first sensor data stream may be, for example, based on a first acceleration sensor and the second data stream may be, for example, based on a second acceleration sensor. I.e., the mobile device 1 comprises an acceleration sensor and the exercising device 2 comprises an acceleration sensor and the acceleration data of both sensors is received by the server 18. The mobile device 1 and the exercising device 2 both measure the same parameter, i.e. acceleration. The sensor of the mobile device 1 may, for example, measure acceleration of a cyclical motion of the right arm of the user as indicated by arrow 7. The sensor of the exercising device 2 may, for example, measure acceleration of the treadmill belt as indicated by arrow 8. According to other embodiments, the sensor of the mobile device 1 and the sensor of the exercising device 2 both measure another parameter, for example angular velocity.

After indication that the devices 1, 2 are engaged with each other has been provided to the exercising device 2 and the mobile device 1, the exercising device 2 may participate in pairing with the mobile device 1 and the mobile device 1 may participate in pairing with the exercising device 2. The mobile device 1 in the form of a wrist-watch comprises at least one processing core and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processing core, cause the mobile device 1 at least to receive a first signal 3 from an exercising device 2, process the received signal, respond to the received signal by transmitting a second signal 4 to the exercising device 2, and participate in a pairing process 5 with the exercise device 2. Further examples are described below in connection with FIG. 2 to FIG. 6.

According to certain embodiments, the apparatus 18 may be further configured to allow a user to remotely read-out at least a part of at least one of the first sensor data stream and the second sensor data stream. In other words, the apparatus 18 is remotely accessible by a person in order to analyse a user session.

The first sensor data stream may be received by the apparatus 18 from the exercising device 2 via wire or a wireless technology, for example a low power wireless communication technology such as Bluetooth, Bluetooth Low Energy, or Wibree. The second sensor data stream may be typically received by the apparatus 18 from the mobile device 1 via a wireless technology, for example a low power wireless communication technology such as Bluetooth, Bluetooth Low Energy, or Wibree.

In FIG. 2 a schematic top view of a mobile device 1 comprised by an arrangement in accordance with at least some embodiments of the present invention is illustrated. The shown mobile device 1 is a wrist-watch. The shown exercising device 2 is a treadmill. The mobile device 1 comprises at least one processing core and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processing core, cause the mobile device 1 at least to receive a first signal 3 from an exercising device 2, process the received signal, respond to the received signal by transmitting a second signal 4 to the exercising device 2, and participate in a pairing process 5 with the exercise device 2. Pairing in accordance with the present invention takes place after indication that the mobile devices 1 and the exercising device 2 are engaged with each other has been provided to the exercising device 2 and the mobile device 1 as described in connection with FIG. 1.

Sensor data contained in the data streams is typically associated with time stamps. For example, one acceleration value is measured every second and for each measured acceleration value the respective time is transmitted to the apparatus 18 in the form of a time stamp. Sensor data from the mobile device 1 having a first time stamp is compared with sensor data from the exercising device 2 having an identical time stamp. This procedure can be repeated for a plurality of second, third, etc. time stamps. When the sensor data from the mobile device and the sensor data from the exercising device correlate with each other, the apparatus is capable of determining that the exercising device 2 is engaged with the mobile device 1. When a user changes an exercising device, for example in a gym, pairing between the new exercising device and the mobile device can be automatically initiated based on the sensor data from the new exercising device correlating with the sensor data from the mobile device 1.

In other words, when a user 6 wearing the wrist-watch 1 starts to use the exercising device 2, sensor data streams are transmitted from the mobile device 1 and the exercising device 2 to the apparatus 18 in the form of a server. The server determines that the exercising device 2 is engaged with the mobile device 1 and estimates an activity type of the user, for example running. Subsequent to providing indication to the exercising device 2 and the mobile device 1 that the devices 1, 2 are engaged with each other, the wrist-watch 1 and the exercising device start to communicate with each other. A first signal as indicated by arrow 3 from the exercising device 2 is transmitted to the wrist-watch 1. Then the received signal 3 is processed by the processing core of the wrist-watch 1. Subsequently, a second signal as indicated by arrow 4 is transmitted from the wrist-watch 1 to the exercising device 2. This process is called pairing 5. Data between the wrist-watch 1 and the exercising device 2 can now be transferred between the wrist-watch 1 and the exercising device 2. Data is typically transferred using low power wireless communication technology such as Bluetooth, Bluetooth Low Energy, or Wibree.

The treadmill belt of the exercising device 2 may be moving with a specific speed as indicated by arrow 8 as a user 6 is running on the belt. At the same time, the arms of the runner 6 move cyclically as indicated by arrow 7. Data may be determined by the sensors of the wrist-watch 1. Examples of such determined data are a heart-beat rate, number of steps during a certain period of time, or acceleration data. Data may also be determined by sensors of the exercising device 2 and transmitted to the mobile device 1. An example of such data is the speed of the moving treadmill belt of the exercising device 2. The information about the speed of the treadmill belt may be transmitted from the exercising device 1 to the wrist-watch 1. The information about the speed of the treadmill belt may then be displayed on the wrist-watch. In other words, the wrist-watch 1 is configured to serve as a display of the exercising device 2. Of course, also data determined by at least one sensor of the wrist-watch 1 may be displayed on the display of the wrist-watch. The user 6 may further choose which data is displayed.

According to certain embodiments, the exercising device 2 may also comprise an additional display and data may be transmitted from the wrist-watch 1 to the exercising device 2. A user 6 may choose which information is shown on the display of the exercising device 2 and which information is at the same time displayed on the display of the wrist-watch 1. In other words, the user 6 may choose which sensor data is displayed on the display of the wrist-watch 1 and which sensor data is displayed on the display of the exercising device 2.

According to certain other embodiments, the mobile device 1 is configured to control parameters or functions of the exercising device 2 after the pairing process 5. In the shown example, a user 6 may control the speed of the treadmill belt of the exercising device 2 as indicated by arrow 8 via a user interface of the wrist-watch 1. A user interface of the wrist watch 1 may be a touchscreen or at least one button, for instance. User instructions to change the speed of the treadmill belt may be transmitted from the wrist-watch 1 to the exercising device 2 and processed by the exercising device 2, thus causing the exercising device 2 to change the speed of the treadmill belt. According to this embodiment, the procedure is typically controlled by the exercising device 2 such that no program code or a minimum amount thereof needs to be installed on the mobile device 1. The mobile device 1 serves as a user interface for the exercising device 2. In other words, a computer program comprising program instructions which, when loaded into the exercising device 2, cause e.g. graphical user interface data to be determined for the mobile device 1 is provided. The graphical user interface data is wirelessly transmitted to the mobile device 1 from the exercising device 2 to provide at least one user interface functionality on the mobile device 1. Then data corresponding to user input is received and wirelessly transmitted to the exercising device 2. Minimum system requirements such as processing capacity and memory capacity are required for the mobile device 1. According to this embodiment, the input data is completely or at least partially processed by the exercising device 2. The bidirectional communication link between the mobile device 1 and the exercising device 2 may be used to enable the exercising device 2 to act as a server having control over the user interface and the mobile device 1 to act as a client whose content is fully or at least partially controlled by the exercising device 2.

In FIG. 3 a schematic side view of a mobile device 1 comprised by another arrangement in accordance with at least some embodiments of the present invention is illustrated. The shown mobile device 1 may be a tablet or other mobile device. The shown exercising device 2 is an ergometer or indoor exercise bike. Prior to pairing, indication that the mobile devices 1 and the exercising device 2 are engaged with each other has been provided to the exercising device 2 and the mobile device 1. After the pairing process as described above in connection with FIG. 2, parameters and/or logics such as an app are transmitted from the exercising device 2 to the mobile device 1. The mobile device 1 is configured to store and process program code received from the exercising device 2. The mobile device 1 is configured to serve as a display of the exercising device 2.

For example, a video simulation of a cycling track may be displayed on the display of the mobile device 1. Thus, the user 6 can cycle along the simulated track. Sensors of the exercising device 2 may determine the cycling speed of the user 6, for example. The sensor data of the exercising device 2 is then transmitted to the mobile device 1. The sensor data can be used as input data for the video simulation displayed on the mobile device 1. In other words, the user 6 can cycle along the virtual track with varying speeds. The visualization of the virtual cycling simulation is calculated based on the speed data obtained from the sensor data of the exercising device 2. On the other side, data may be transmitted from the mobile device 1 to the exercising device 2, thus causing the exercising device to change a parameter. Altitude data along the virtual track stored in the app may be provided, for instance. The altitude data can be used as input data for the parameters of the exercising device 2 as a function of time. When the data is received by the exercising device 2, it causes the exercising device 2 to change the resistance of the exercise bike during cycling along the virtual track. In other words, cycling upwards or downwards along the virtual track can be simulated. The exercising device 2 is configured to transmit sensor data to the mobile device 1 and to receive in response input parameters from the mobile device 1. Consequently, cycling along a virtual track, for example a passage of the Tour de France, can be simulated.

The exercising device 2 may be, for example, located in a gym and different users may subsequently cycle along the virtual track. When each user bring his/her own mobile device 1 to the gym, for each user a period of time may be determined by the app for cycling from the beginning of the virtual track to the end of the virtual track. The period of time for each user may then be transmitted from the respective mobile device 1 to the exercising device 2 and stored in a memory of the exercising device 2. The different periods of time may be ranked and listed so that a user can see his/her results in comparison to the results of other users. Thus, it is possible to simulate a cycling competition, for instance.

Of course, the mobile device 1 may also be used for displaying only information such as cycling speed, length of cycling session period or for selecting a cycling resistance of the exercising device 2.

Data determined by sensors of the exercising device 2 may be received by and stored in the mobile device 1. Alternatively, data determined by sensors of the exercising device 2 may be received by the mobile device and stored in the cloud. Thus, the user 6 can analyse the stored data at a later stage by reading out the memory of the mobile device 1 or viewing a webpage in the internet.

In FIG. 4 a schematic side view of an exercising device 2 comprised by a further arrangement in accordance with at least some embodiments of the present invention is illustrated. In the shown embodiment, the exercising device 2 is a rowing machine. The mobile device 1 may be a tablet computer, for instance. The exercising device 2 comprises at least one processing core 13 and at least one memory 14 including computer program code. The at least one memory 14 and the computer program code are configured to, with the at least one processing core 13, cause the exercising device 2 at least to transmit a first signal 3 to a mobile device 1, receive a second signal 4 from the mobile device 1, and participate in pairing 5 with the mobile device 1. Prior to pairing, indication that the mobile devices 1 and the exercising device 2 are engaged with each other has been provided to the exercising device 2 and the mobile device 1.

Subsequent to the pairing process 5, program code to be stored and processed by the mobile device 1 can be transmitted from the exercising device 2. Parameters and/or logics such as a rule engine, an app, a classification recipe or a html web page can be transmitted to the mobile device, for instance.

For example, an app may be transmitted to the mobile device 1. A user can select a training program with the help of the app. During the training session, the exercising device 2 may, for example, transmit a recipe or an instruction to the mobile device 1 how to analyse movements of a user 6. The movements of the user may be determined or recorded using sensors of the exercising device 2. Examples of such sensors of the exercising device are force sensors and acceleration sensors. Data determined by the sensors of the exercising device 2 may be shown on a display 15 of the mobile device 1.

A user can further input data using a user interface 17 of the mobile device 1. A user interface 17 may be, for example, a touchscreen, a button, a keyboard or an optical system analysing gestures of the user. The exercising device 2 is capable of receiving the data which has been input via the user interface 17 of the mobile device 1. The exercising device 2 is capable of receiving instructions from the mobile device 1. For example, another training program may be selected.

According to certain embodiments, a first exercising device 2 and a first mobile device 1 in accordance with at least some embodiments form a first unit and a second exercising device 2 and a second mobile device 1 in accordance with at least some embodiments form a second unit. The first unit and the second unit are capable of communicating with each other. For example, rowing of a rowing boat having two seats can be simulated. Subsequent to starting of a specific training program, two users simultaneously using respective exercising devices have to synchronize their movements in order to row a virtual rowing boat. A first user is then virtually in the position of the person sitting in front of the other person. Thus, a sports team can train rowing of a rowing boat, for example in winter time when training with a real rowing boat is not possible due to weather conditions.

In FIG. 5 a schematic top view of a mobile device 1 comprised by a yet further arrangement in accordance with at least some embodiments of the present invention is illustrated. The exercising device 2 includes an audio system 9. Prior to pairing, indication that the mobile devices 1 and the exercising device 2 are engaged with each other has been provided to the exercising device 2 and the mobile device 1. After the pairing process 5 as described above in connection with FIG. 1, a music program can be started or stopped, a volume of music can be controlled and/or a title can be selected using the mobile device 1 in the form of a wrist-watch 1. According to this embodiment, the procedure is typically fully or at least partially controlled by the exercising device 2 such that no program code or a minimum amount thereof needs to be installed on the mobile device 1. The mobile device 1 serves as a user interface for the exercising device 2. In other words, a computer program comprising program instructions which, when loaded into the exercising device 2, cause e.g. graphical user interface data to be determined for the mobile device 1 is provided. The graphical user interface data is wirelessly transmitted to the mobile device 1 from the exercising device 2 to provide at least one user interface functionality on the mobile device 1. Then data corresponding to user input is received and wirelessly transmitted to the exercising device 2. Minimum system requirements such as processing capacity and memory capacity are required for the mobile device 1. According to this embodiment, the input data is completely or at least partially processed by the exercising device 2. The bidirectional communication link between the mobile device 1 and the exercising device 2 may be used to enable the exercising device 2 to act as a server having control over the user interface and the mobile device 1 to act as a client whose content is fully or at least partially controlled by the exercising device 2.

Alternatively, a provided further, second mobile device (not shown), for example a smartphone, may include an audio system. In such a case, a music program can be started or stopped, a volume of music can be controlled and/or a title can be selected using the wrist-watch 1 after the pairing process 5 between the mobile device 1 and the exercising device 2. In other words, the mobile device 1 may be used to additionally control functions of a further second mobile device. According to this embodiment, the procedure is typically fully or at least partially controlled by the second mobile device such that no program code or a minimum amount thereof needs to be installed on the mobile device 1 such as a wrist-watch. The mobile device 1 serves as a user interface for the second mobile device. In other words, a computer program comprising program instructions which, when loaded into the second mobile device, cause e.g. graphical user interface data to be determined for the mobile device 1 is provided. The graphical user interface data is wirelessly transmitted to the mobile device 1 from the second mobile device to provide at least one user interface functionality on the mobile device 1. Then data corresponding to user input is received and wirelessly transmitted to the second mobile device. Minimum system requirements such as processing capacity and memory capacity are required for the mobile device 1. According to this embodiment, the input data is completely or at least partially processed by the second mobile device. The bidirectional communication link between the mobile device 1 and the second mobile device may be used to enable the second mobile device to act as a server having control over the user interface and the mobile device 1 to act as a client whose content is fully or at least partially controlled by the second mobile device.

In FIG. 6 a schematic side view of an exercising device 2 comprised by a yet further arrangement in accordance with at least some embodiments of the present invention is illustrated. The shown exercising device 2 is an ergometer in the form of an indoor exercise bike. The exercising device 2 comprises at least one processing core and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processing core, cause the exercising device at least to transmit a first signal to an mobile device 1, receive a second signal from the mobile device 1, and participate in pairing with the mobile device 1. Prior to pairing, indication that the mobile devices 1 and the exercising device 2 are engaged with each other has been provided to the exercising device 2 and the mobile device 1. The exercising device 2 further comprises a video system 10. The video system 10 may be, for example, a TV, a tablet, or a PC. The mobile device 1 may be used as a remote control of the video system 10.

A wrist-watch is shown as the mobile device 1. Typically, the exercising device 2 is configured to transmit the first signal and to receive the second signal when a distance between the mobile device 1 and the exercise device 2 is about 0 m-10 m. In other words, the pairing process is activated when a user 6 with the wrist-watch 1 is moving closer to the exercising device 2. After the pairing process between the mobile device 1 and the exercising device 2, data can be transmitted between the mobile device 1 and the exercising device 2. For example, the user 6 may select a TV channel to be shown on the video system 10 by the wrist-watch 1. The wrist-watch 1 can therefore serve as a remote control when cycling. Alternatively, data obtained by sensors of the mobile device 1, for example heart beat data, and data obtained by sensors of the exercising device 2, for example speed data, may be displayed on the video system 10. The exercising device 2 is configured to participate in the pairing process during a session with the mobile device 1. The session is based on sensors of the mobile device 1 and the exercising device 2.

In FIG. 7 a schematic view of an arrangement in accordance with at least some embodiments of the present invention is illustrated. FIG. 7 represents a situation in a gym with different exercising devices 2, for instance. The arrangement comprises an apparatus 18 comprising at least one processing core and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processing core, cause the apparatus 18 at least to receive a first sensor data stream from an exercising device 2, receive a second sensor data stream from a mobile device 1, correlate the first data stream with the second data stream, determine that the exercising device 2 is engaged with the mobile device 1, and provide indication to the exercising device 2 and the mobile device 1 that the devices 1, 2 are engaged with each other. In the shown example, four mobile devices 1 and four exercising devices 2 are illustrated. One mobile device 1 and one exercising device 2 form a single unit. In other words, four separate units are shown in FIG. 7. The apparatus 18 in the form of a server receives from three units a first sensor data stream from a sensor of the respective exercising device 2 and a second data stream from a sensor of a respective mobile device 1. For each unit, indication to the respective exercising device 2 and the respective mobile device 1 that the devices 1, 2 are engaged with each other is being provided and pairing between the devices 1, 2 of each unit can start. For each unit an activity type of a user, for example running, cycling and rowing, can be estimated. From the fourth unit no sensor data streams are received by the apparatus 18, i.e. the fourth unit is not in use and therefore no activity type can be estimated.

The server 18 is configured to estimate an activity type of different users based on the correlated data streams of a unit. In other words, the server 18 is capable of estimating if a person is cycling, running or rowing based on the correlated data. Data determined by sensors of each mobile device 1 and each respective exercising device 2 may be stored on the server. The server 18 is remotely accessible in order to analyse a user session at a later stage for each unit.

A user may use different exercising devices 2 in a gym, for example a treadmill first and then a cross trainer. Due to the correlated data streams and the time stamps associated with the sensor data contained in the data streams, thus e.g. indicating a start time and an end time of an activity type, pairing between a first exercising device and the mobile device can be automatically initiated first and pairing between a different second exercising device and the mobile device can be automatically initiated at a later stage.
